- Abstract
In thylakoids of cyanobacteria and other photosynthetic organisms, the light-induced production of molecular oxygen is catalyzed by the giant lipid-pigment-protein complex called photosystem II (PSII). The oxygen-evolving complex is buried deep in the lumenal part of PSII, and dioxygen molecules need to pass through the protein environment in order to leave the active site of the enzyme free. Previous studies aimed at finding oxygen channels in PSII were based on either an analysis of the cavities within is static structure or experiments on the insertion of noble gas molecules into PSII crystals under elevated pressure. In these studies, some possible exit pathways for the molecules were found and the static positions of molecular oxygen were determined. In the present work, the oxygen movement in the transport system of PSII is simulated by molecular dynamics.
